This thread seems similar and includes additional information. It might help you as well:

Excessively Large URI Generation During Concordium Identity Workflow

It generates the link like this https://id-service.testnet.concordium.com/api/v1/www.gatewayapp.co/confirm-identity#error=Duplicate%20idCredPub which, when opened, shows internal server error on the browser [Screenshot 2024-03-12 at 15.46.54] Appears to be complaining of a duplicate, not sure. Is there a way to work around this? Maybe check status and retrieve instead to prevent this error?

The reply might help you:

@Manuel

const identityIndex = 0;

This will determine your “idCredPub” which needs to be unique when requesting an identity.

Have you looked at the flow description concordium-base/identity-provider-service at main · Concordium/concordium-base · GitHub ?

The flow is designed with redirects in mind. When you initiate a flow you supply the URI to which you want to be redirected to. In the example wallet that is set to this concordium-node-sdk-js/examples/wallet/src/util.ts at 6724364de8e7b4d4086aec0bf379f965b7cf781c · Concordium/concordium-node-sdk-js · GitHub

In your case that appears to be www.gatewayapp.co/

You want to intercept that redirect and handle it like the example wallet does concordium-node-sdk-js/examples/wallet/src/CreateIdentity.tsx at main · Concordium/concordium-node-sdk-js · GitHub

If it doesn’t help, can you provide more information what you are trying to do that gives you the above error.
